Abstract: ABSTRACT OF THE DISCLOSURE:           A method of strengthening propellent charge powder bodies, which comprises applying to a propellent charge green grain powder obtained during the production thereof an ester or dinitrile of an aliphatic dicarboxylic acid.  The method of the invention enables one to obtain propellent powder bodies whose internal ballistic properties undergo practically no change at temperatures above 0°C, in relation to the internal ballistic properties of untreated propellent powder bodies.  Moreover, when firing at low temperatures, on the other hand, decided improvements over the ballistic properties of untreated propellent powder bodies are obtained.  Neither premature increases in gas pressure nor an ominously broad pressure band occur.  The improvements are particularly noticeable when the propellent powder bodies are subject to high impact force or to a rapid rate of pressure increase.

Abstract: METHOD AND APPARATUS FOR RESTORING BADLY DISCOLORED, FRACTURED OR CARIOUSLY INVOLVED TEETH     ABSTRACT OF THE DISCLOSURE         A method and apparatus for restoring badly discolored, fractured or cariously involved teeth by etching desirable parts of the enamel surface of the tooth and by adhering to the tooth a properly colored polymerized, preformed plastic facing that has a pleasing cosmetic appearance or corresponds to the color-ing of adjacent teeth as desired.  The etched surface of the tooth, the inside surface of the facing material and the exposed surface of the facing material including the joint between the facing material and the enamel of the tooth are coated with a controlled curing dental adhesive material that may be selectively cured in place, such as by ultra-violet activation.  The voids between the tooth and the facing material may be filled with a controlled curing dental filler material that may also be molded about the joint between the tooth enamel and the facing material.          The dental filler material may also be of the type that is cured in place such as by curing following ultra-violet activation.          Facings bonded to the enamel of abutment teeth may be employed for support of pontics without necessitating preparation of abutment teeth with bridgework support crowns.  Connected facings may also be employed for periodontic splinting.

Abstract: ABSTRACT OF THE DISCLOSURE      A centrifuge device and method are provided for separating and/or washing finely-divided solid particulate material suspended in a liquid.  The invention is especially useful in so treating blood.  The centrifuge forms a dense suspension of blood cells in a plurality of blood cells receiving means evenly spaced about the periphery of a rotatable enclosure.  The receiving means have converging walls which at their juncture form a locus of maximum centrifugal force.  Wash liquid is passed through the dense suspension of blood cells counter to the direction of the centrifugal force by entry into the blood cell receiving means at the locus of maximum centrifugal force.  Independent conduits connect the locus of maximum centrifugal force through an injector to a supply for the wash liquid and, after fully resuspending the blood cells in a suitable resuspending liquid, the resuspended cells exit from the centrifuge via the independent conduits and injector, which have also therefore been washed by the wash liquid.  Thus recontamination is avoided.  A unitary disposable structure including the enclosure, blood cell receiving means, conduits and injector is also provided.
